More money by teamsets IF they all sell. The problem you get with teamsets is that you will quickly sell out of Dragons/Eels/Tigers and a few other very popular teams but you'll be left with a heap of team sets from Panthers/Raiders/Cowboys etc. So you either alter the price slightly to compensate...or just sell as sets to get them out the door with less fuss.
Just be aware if it's NRL Dynasty then the price for sets will be bottom of the barrell right now as all the big sellers look to dump them fast.
